Hello,

I'm putting the entire sub below and asking if anyone can help answer what
is wrong with it. I am receiving an error at the first parameter line:

OraCommand.Parameters.Add("v_ACT_EMAIL_ADDRESS1_IN",
OleDb.OleDbType.VarWChar, 60)

saying:

'BEGIN ERROR DESCRIPTION
Description: An error occurred during the compilation of a resource required

and modify your source code appropriately.

Can anyone please let me know what I am omitting here...this is driving me
crazy!

On line 84 you seem to be referencing the object 'OleDb.OleDbType.VarWChar',
forgive me if I'm wrong, but shouldn't this be
'System.Data.OleDb.OleDbType.VarWChar'?

Wouldn't it be quicker to use the OracleClient instead of the standard OleDB
client?

Bruce
 
Bruce,

Thanks for the quick reply. Can you please show me in a small example of
how I would use the OracleClient in this situation?

Karl
 
Here is an article that helped me with .NET and Oracle. Pay attention to the
OleDb sections, if you are sticking with the OleDb client.

http://msdn.microsoft.com/library/en-us/dndotnet/html/manprooracperf.asp

In general, I set up the parameter direction, et al, on the object when it
is created, like so:

OleDbParameter param1 = new OleDbParameter("USER_NUMBER",OleDbType.VarChar ,
250, ParameterDirection.Input, false, 0, 0,
"USER_NUMBER", DataRowVersion.Default, userNumber);

I also end up with a parameter object that is explicitly created, rather
than have to go at the parameter, by name, later on. This gives me the
ability to use:

param1.Direction = ParameterDirection.Input

The article mentioned is written in C#, so you will have to watch a bit to
get the gist.
